Crossposted from the Email Category

We have been seeing an increasing number of these 'bogus' form submissions with clients of ours that have online email forms, and have developed a way to prevent such submisssions. If your are using ASP for your form, simply add the code below to the top of your form's ACTION page:

<%
if Request.ServerVariables("HTTP_REFERER") <> "http://yourdomain.xyz/yourForm.html" then
response.redirect("http://yourdomain.xyz/someErrorpage.html")
end if
%>

Note that this script:

http://yourdomain.xyz/yourForm.html - this is the page where your actual form is
http://yourdomain.xyz/someErrorpage.html - this is the page you want the user to be redirected to if they try and post information to your form from some location other than your form page.
